Hi!
I have a bonded trio, but agree with Wick, it’s strange advice as its not the easiest way of creating bonded bunnies. That said, a bonded trio is extremely cute! I’ve heard that sometimes you end up with a bonded pair and another rabbit sort of tagging along, but mine all spend equal-ish amounts of time together and I can’t see anyone being left out.
Unfortunately you won’t be able to bond them until all are neutered and spayed, so I image it’s at least 4/5 months away until the babies can be neutered/spayed. Is Bugsy spayed?
For now, I would recommend housing them all separately, and swapping them between cages every other day, so that they all get used to the scents of each other. This is known as prebonding. Once they’re neutered, they need to be given a month for hormones to drain, in which time you can continue prebonding. THEN you can get to the actual bonding.
I knew that one of my bunnies was going to be very difficult, so I started on the easy pair, and then added her once I knew there wouldn’t be trouble. I also experimented with the separate pairings to get them all used to each other. In all, it took me about a month of bonding sessions to call them a trio, but I had been prebonding for months before that. I would be happy to give you more tailored advice when you get closer to it
